ABSTRACT:
Novel triazine derivatives which are with cyanoacetic acid, derivatives of cyanoacetic acid or malodinitrile substituted s-triazines and which provide stabilizers against ultraviolet radiation for organic polymers such as polyvinyl chloride or copolymers of polyvinyl chloride or polypropylene are obtained by reacting the corresponding chloro-s-triazinyl derivatives with sodium hydride or a metal lower alcoholate in an organic solvent, and isolating the resulting product by acidification.
